MULTI-BOX MBP-Ex i junction boxes made of reinforced polyester meet all the requirements for facilities where explosive concentrations of gases, vapors and dust can occur (zones 1 and 2, as well as 21 and 22).
MBP-Ex i enclosures can be used for temperature classes T4 to T5.
The explosion protection of the so-called intrinsically safe enclosures of type “i” is based on the use of low voltage and the connection of power supply to the enclosure (for example, for data transmission or for telephone communication).
Due to the limitation of the ignition energy, the appearance of a spark is absolutely impossible. Even a temperature rise or heating of our Ex i junction boxes, assembled with the maximum number of serial contacts, cannot cause an explosion. Graphite additives in the polyester material prevent static charge on the surface of the casing with the help of low surface resistance = lt; 10 * 9 Ohm.
In order to separate the intrinsically safe power circuit when installing Ex i enclosures, you must select the blue or blue marked cable glands and blue contacts.
